Orchard Park, N.Y. -- After Patriots offensive coordinator Josh McDaniels accepted and then backed out of the Indianapolis Colts' head-coaching job, the Colts have now turned their attention to one of the Buffalo Bills' top assistants.

As Ian Rapoport of NFL Network first reported, the Colts have officially requested permission to interview Bills defensive coordinator Leslie Frazier for their head-coaching vacancy.

Frazier, who was previously the head coach of the Minnesota Vikings, has a 21-32-1 record as an NFL head coach with one playoff appearance. He joined Sean McDermott's staff as defensive coordinator after spending the 2014 and 2015 seasons as the Buccaneers' defensive coordinator and the 2016 season as the Baltimore Ravens' secondary coach.

While the Bills' success on defense in 2017 has mostly been credited to McDermott, who has a defensive background, the Bills' first-year head coach was quick to credit Frazier for his poise and leadership behind closed doors. Frazier was someone McDermott was able to lean on during difficult times this season because of Frazier's experience as a head coach.

At this point, the Colts could certainly use some stability in the organization, so interviewing Frazier makes sense.
